It might be helpful to remove the animation of the chest moving when you're clicking. It seems to cause quite a bit of lag and stops clicks from registering for chunks of time. This causes skills to lose considerable income with the loss of those clicks.
Currently they're just fun milestones, they'll be dropping a new currency in a future update though ... oh and Aidith will still get Gems when you kill them.
I like the new update. I have to admit I was frustrated at first to have to sacrifice a good chunk of my dps to get back the cool down reduction but in the long run there is a lot more potential for improving now.
My All Time Cash Earned isn't working properly. Since I reset after the updates I've made significantly more money than is recorded. At one time I even had more cash on me than it showed I had made total.
